'UNITED STATES PATENT OFFICE.

SQUIRE B. RUDE, GEORGE W. RUDE, AND JOHN R. RUDE, OF LIBERTY, INDIANA, ASSIGNORS TO THE RUDE BROTHERS MANUFACTURING COMPANY, OF SAME PLACE.

GRAIN- DRILL.

To all whom it may concern:

Be it known that we, SQUIRE B. RUDE, GEORGE W. RUDE, and JOHN R. RUDE, citizens ofthe United States, residing at Liberty, Union county, Indiana, have invented certain new and useful Improvements in Grain-Drills, ot' which the following is a specitication.

This invention relates to certain improvements in grain-drills; and it consists, first, in the novel manner ot' attaching the receivingspout to the seed-cup; and, secondly, to the construction and adjustment ofthe rubber tube to the receiving-spout, whereby the said tube can readily conform to the proper position when the hoes are shifted from a double to a single rank, or vice versa.

In the annexed drawings, Figure l is aside elevation of the seed-cup and receiving-spout, showing them disconnected, the extension on the receiving-spout being partly out away, so as to more fully show the connecting-groove. Fig. 2 is also a side elevation ot' the seed-cup and receiving-spout, showing them together, and also showing the exible tube attached to the receiving-spout; and Fig. 3 is an enlarged rear sectional view of the bolt mechanism, showing the same locking the seed-cup and receiving-spout together.

The letter D represents the seed-cup or second-ary hopper, formed with a downward eX- tension, C, provided with side flanges, constituting a T- shaped lug, as better seen in Fig. Softhe drawings. This seed-cup is also formed at the front end of the extension O with arecess or chamber and slot for the reception and lmovement of the bolt E and its handle a, serving as a finger means to lift the bolt.

The letter A represents the receiving-spout, with the forward grooved lug or ear, B, arranged preferably at an angle, and adapted to pass over the side ilanges ot' the seed 'cup extension, as shown. When the attachment of the spout to the seed-cup is made the bolt E drops automatically into a socket or notch in the upper surface of the lug or ear B, and locks the parts irmly together for the co-operation.

The letter F indicates the end of the slide, as seen on the outside of the seed-cup, which Patent No. 275,862, dated April 17, 188s,

Renewed March 12, 1883. (Model.)

controls the amount of seed fed to the feedwheel.

G is the washer, which assists in keeping said slide in place.

H is the shaft, which works the slide and also revolves the feed-wheel.

The letter I represents the rubber tube for conveying the seed from the cup to the hoes. Heretofore these tubes have been made of the same thickness throughout and attached to the receiving-spout, which was either cast with the seed-cup or rigidlysecured thereto. Also, these tubes have been attached in various other ways; but they did not always allow of an even tlow of the grain, because ofthe rubber bending or pinching, thus narrowing and frequently choking the bore-passage. We remove this objection by making a portion of the tube thin and iiexible, some two or three inches in length, at or near the point where the tube is attached tothe receiving-spout; or this thin flexible portion of the tubemay be some distance below-say about th middle ot' the tube. This flexibility enables the tube to adjust itself to the position of the hoes when shifted from a double to a single rank, or vice versa, without in any way collapsing or impeding the evenness of the liow of grain.l

The extension or projections of the seed cup and spout are cast therewith, and the bolt E is not alone depended upon for securely holding the parts together, since the extension C is inclined, and when united to the grainspout the latter, by its own weight and the weight of the tube attached to it, will bear against the seed-cup, thereby holding them together by frictional contact; but for greater security we have added the bolt.

What we claim as our invention, and desire to secure by Letters Paten t, is-

1. A seed-cup for a graindrill, formed with a downward extension,constituting an attaching means, and provided with a locking-bolt, substantially as described.

2. A grain-spout for a grain-drill, formed with a forward grooved lug or ear, B, arranged at an angle and adapted to be connected to a seed-cup by frictional contact, substantially as described.

3. The combination of a seed-cup formed with a downward extension, constituting an attaching device, and provided with a lockingbolt, and a grain-spout formed with an inclined grooved lug passed over the coupling device of the seed-cup and locked thereto, substantially as described.

4. The combination, with the seed-cups or receiving-spouts of a grain-drill and its hoes, 1o ot' rubber tubes containing thin elastic flexible portions, whereby the tubes may adapt themselves to the position of the hoes without pinching or buckling, substantially as set forth.
